Letters Patent No. 83,967, dated November 10, 1868.

IMPROVEMENT IN RETAININGDEVICE FOR DOORS, 8m.

The Schedule rean-ed to in these Letters Patent and making bart of the sam To all whom Iit may conccrn.

Be it known that I, LEVI T. HowELL,.of Camden, Camden county, New Jersey, have invented an Iniproved Portable Retaining-Device for Shutters, Doors, &c. and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention consists of a device, constructed as fully described hereafter', so that when applied to the hinge of a shutter or door, it Ywill 'retain 1the latter in the position to which it has -been' adjusted, the device being portable, cheap, and simple in its construction.

In order to enable others skilled in the art to make and use my invention, Lwill now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Fignre 1 represents in perspective a window-frame and shutter, with my improved retaining-device applied to the hinge of the shutter;

Figure 2, a section on the line 1-2, iig. 1;

Figures 3, 4, and 5, detached views, drawn to aneularged scale; and

y Figure o', a perspective View ofa modification.

At the inner side of a bent plate, A, near one vedge of the saine, is a projection, a, and on the latter is a lip or lug, b, which extends downward, parallel, or nearly parallel, with the plate A, a knob, c, being secured to the upper side of the said projeetion.

The device is applied to the hinge, I5, of a shutter or do0r,'as shown in the drawing, the cinvature ofthe plate A being such, that when its ends bear upon the opposite plates of the hinge, (Iig. 3,) the central portion will extend over the lib formed bythe junction of I the two plates, the projection a resting upon the upper edge of the hinge, and the lug b being opposite to and' bearing against the inner side ofthe hinge, as shown in gs. 1 and 5.

It will be apparent'that so long asthe plate remains in its position, bearing against both plates of the hinge, the latter, and the shutter or door to which it is attached, cannot be closed, and that no jarring to which the shutter or door is liable will be suicient to detach the de vieev from its place. i

W'hen' the shutter is to be closed, the fastening-device is merely lifted from its place, and its loss maybe prevented by securing it to one end of a chain or cord, attached at the otherl end to any adjacent fixture. In this case the knob may be dispensed with, as shown in tig. 6.

'It will be apparent that this device may be applied to the hinges oi'doors, boxes, Sec., and may be so formed as to retain the hinge 'in a partly-opened position.

I claim as my invention, and dsire to secure by Letters Patent- A retaining-device, consisting of a curved plate, A, its projection ar` and lug b extending from t-lieprojectio'n parallel to the plate, all substantially as and for the purpose described.

In testimony whereof, I have signed my naine to this specification, in the presence of two subscribing witnesses.

LEVI T. HOWELL.
